About vertical.solar

Started by Over Easy Solar in January 2022, the vertical.solar research project develops data and knowledge necessary for developing the first commercial product by Over Easy Solar: the light weight, vertically mounted bifacial PV unit. As this is a new combination of PV components there are knowledge gaps regarding the technology. This project aims at developing a better understanding of the performance of this unique PV system, of the response to different external environmental factors on the performance of the VPV units and of optimizing the VPV units. The project is divided into four different workpackages: WP1 energy yield, WP2 wind load, WP3 materials & durability and WP4 product sustainability. Project partners are Institute for Energy Technology (IFE) and Fraunhofer Institute for Solar Energy Systems.
